Uber and Lyft are being blamed for most of the traffic in San Francisco

Lame article.

How have Lyft and Uber contributed to the drop in DUIs and drunk driving in general?

What about accidents? Insurance claims? Slower traffic was advertised as better for decades, for fuel safety etc.

What this shows to me is the city needs to figure out how to adapt it's relationship to cars in general.

I hate cars, the city should be thinking about how to eliminate the need for cars in it's limits as much as possible.
